a front funnel portion;
a plurality of gamma detectors housed inside the medical image scanner gantry and positioned behind the front funnel portion that comprises:
an annular interior wall defining an entry opening of the patient tunnel portion; and
an air plenum comprising an annular structure for carrying a flow of pressurized air received from a remote source, wherein the air plenum comprising an annular nozzle configured for directing the flow of pressurized air toward the plurality of gamma detectors as a flow of high-velocity air for cooling the plurality of gamma detectors and their associated electronic components;
